In a former job I used to buy plastic enclosures from a company that would machine/paint/silk screen them per my specifications. They would also spray the inside with a conductive paint for RF

Dear All, I may have missed this information in the flow of Bitx posts: Has anyone compared the performance of Asshar's AGC circuit against that of Peter's (VK3YE) AGC circuit using the LED + LDR. If

The guy who turned me onto the BITX 40 got the analog one shortly before I got the digital tuning one. He had the same parts, but not assembled like the Raduino. It made sense to him to run the

I followed KV4QB?s advice and put a 10uF between 1 and 8 on the LM386. It got the audio up again. The AGC is somewhat working, but strong signals are still quite loud. Any ideas how this could be

Good evening folks. I'm hoping someone out there can give another assist with the Arduino code. I'm getting pretty frustrated with this thing and I just can't find the part(s) of the code I'm getting

I am using a 2167, it is a newer part and gives you both speech compression as well as a noise gate. It also allowed me to switch to a dynamic mike. v/r Fred W4JLE Sent: Sunday, February 26, 2017

The Vu2xes layout for mounting /g/BITX20/files/Enclosures_Metal_or_Plastic/Metal_Box_files/vu2xes_Aluminum_Case

I made two kits, chosen for their audible side tone. The way the BITX seems setup to work CW is audio cable mic level input. Not line in level input. And especially not headphone level output. Phone

I had the same issue too, the carrier was not properly suppressed. My wattmeter was reading about 200mW with PTT on and no modulation. I found that the balance potentiometer R105 was not adjusted

When I see here:” RADUINO AND CABLE FOR $3.47 USD WITH FREE SHIPPING” I come to think it is not about a Raduino but about an Arduino. Most UNO copies on ebay come with a cable and are in this

I'm not sure, but my guess is that Ralph is hearing the residual carrier from the BITX when he keys the PTT and listens on another rig.? The carrier is suppressed but it is still there and will be

HERE IS SOMETHING ELSE TO PONDER. HAVE YOU EVER BUILT ONE OF THOSE " PIXIE" QRP 7MHZ TRANSCEIVERS FOR UNDER FIVE BUCKS? THEY DON'T HAVE A TONE WHEN YOU TRANSMIT. BUT, I'VE MADE MANY CONTACTS WITH A

How about links to the eBay items that you bought. The emails you posted don't provide any help. Thanks, Roy WA0YMH Carrollton TX

FOR THE ARDUINO NANO AND CABLE TRY..... wuha00711@... (sensesmart 6218) FOR THE DISPLAY TRY....15423949@... OR JUST DO A "SEARCH" ON E-BAY, THERE ARE SEVERAL DEALERS SELLING THESE

There are a lot of C books out there and many that are aimed specifically at the Arduino population. Since you are working from a non-beginner programming background, you may want to skip an intro

I've been asking about this my self. In the code is function button for different modes and functions. One is CW mode which requires the external use of a transistor to hold PTT for a bit while cw

Can you send a link for this?
